What Is Geothermal Energy?
Geothermal heat pumps are among the most efficient and comfortable heating and cooling technologies, but instead of using heat found in outside air, they rely on the stable, even heat of the earth to provide heating, air conditioning and hot water. The heat pump equipment works like a reversible refrigerator by removing heat from one location and depositing it in another location. Installing a commercial geothermal heat pump system will save energy and help you save money on utility bills.
Geothermal heat pumps can be open- or closed-loop. Open-loop systems draw well water for use as the heat source or heat sink, and after use, return the well water to a drainage field or another well. Closed-loop or earth-coupled systems use a water and antifreeze solution, circulated in a ground loop of pipe to extract heat from the earth. Special heat pump features can include variable speed blowers and multiple-speed compressors. Add-on features include the capability to produce hot water.
The earth’s constant temperature is what makes geothermal heat pumps one of the most efficient, comfortable, and quiet heating and cooling technologies available today. Geothermal systems average 40 percent greater efficiency than air-source heat pumps, 48 percent better than natural gas furnaces and 75 percent better than oil furnaces.
The Benefits Of Geothermal Energy
